INSTRUMENT PANEL - FUNCTIONAL DESCRIPTION

1.8 T.SPARK, 2.0 JTS

Functional description

The ignition-operated power supply (INT) of the instrument panel

E50

reaches pin 1 of connector A through the line of fuse F37 of the unit under the dashboard

B2

; the direct supply reaches pin 2 of connector A through the line of fuse F53 of the unit under the dashboard

B2

; pin 7 of connector A is earthed (earth controlled by the Body Computer

M1

).

The instrument panel

E50 is connected from pins 3 and 4 of connector A to the Body Computer M1 and via the latter to the whole CAN network: via CAN the signal for the electronic speedometer arrives (coming from the ABS control unit M50): this signal is replicated from pin 37 of M50 to pin 17 of connector A of the Body Computer M1.

The electronic rev counter receives the rpm signal coming via CAN from the engine management control unit

M10

The fuel gauge is controlled in accordance with the signals coming from the fuel gauge sender unit located in the fuel pump assembly

N40

- at pins 4 and 15 of the Body Computer

M1

, and from here via CAN to the instrument panel

E50

The seat belt warning light is controlled by a signal sent to pin 15 of connector A of

E50

from switch

I45

The inertia switch warning light is controlled in accordance with the signal which reaches pin 12 of connector A of

E50

from the relevant switch

I50

(N.O. contact: the N.C. contact is the one which interrupts the operation of the petrol pump

The brake pad wear warning light is controlled in accordance with the signal which reaches pin 23 of connector A of the Body Computer

M1

from the relevant sensor

K20

See E5030 PETROL ENGINE ELECTRONIC MANAGEMENT

The low brake fluid/handbrake applied warning light comes on through a signal from the handbrake switch

I40

, which reaches pin 24 of connector E of the Body Computer

M1

, or from the signal from the low brake fluid level sensor

K25

, which reaches pin 18 of connector A of

M1

All these signals are transferred via CAN to the instrument panel

E50
